I have an ESC overheating problem. I'm wondering if a tight belt and tight motor to gear spacing can have that effect? Do pilots check overall drag and friction on helicopters after repairs or upgrades?

I know how Icarus felt

Belt should not be overly tight should be able to "push in" on it, motor to main gear can cause this, I use a 1/4 in wide piece of paper for spacing between them, put paper between and squeeze the two of them and tighten up the motor screws then turn the main gear a spin the paper out it should be crinkeld. Well that's how I've been doing it for years hope it helps

Did you change to an 11T pinion like I suggested in your previous topic?

The belt should not be tight like a guitar string but also you don't want it flapping around inside the boom. I like to give the boom a very gentle pull with the screws/bolts slackened off just enough to take the slack out and tighten the screws/bolts.

To set the pinion i've never used the paper method as it can still be too tight after the motor mount screws have been tightened. I like to feel a slight 'click' of play as I move the main gear back and forth with my fingers, although I guess you can do this as a check after doing the paper method.

60% of the time, it works every time!

As mentioned, did you change gearing ratio?

I'm wondering if a tight belt and tight motor to gear spacing can have that effect?
Yes, its a contributing factor. More drag requires more force to overcome and in electrics its expressed in heat dissipation via electronic components. Also loss performance,less flight time and possibly shorter lifespan such as the ESC burning up which can trickle effect into other components.

Do pilots check overall drag and friction on helicopters after repairs or upgrades?
The smart ones do.

Kidding aside, a repair or upgrade should not be treated any different than a new build.
